This problem became visible during the make check phase when creating packaged
on the listed archs for horst[1]. You can see a build logs at
https://buildd.debian.org/status/fetch.php?pkg=horst&arch=s390x&ver=5.0-1&stamp=1503905687&raw=0
https://buildd.debian.org/status/fetch.php?pkg=horst&arch=ppc64el&ver=5.0-1&stamp=1503906226&raw=0
The error message looks identical (I checked the ppc64el log) to the
problem with backend/sum.c:
sparse -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=.
-fstack-protector-strong -Wformat -Werror=format-security -std=gnu99 -Wall
-Wextra -g -I. -DDO_DEBUG -I/usr/include/libnl3 *.[ch]
/usr/include/powerpc64le-linux-gnu/gnu/stubs.h:8:12: error: unable to
open 'gnu/stubs-32.h'
Makefile:113: recipe for target 'check' failed
make[1]: *** [check] Error 1
